Neither the weighing or similar machinenor the packaging device of the invention may be associated are shown in the drawings, because the nature of machines in these categories are well understood and their construction forms no part of the pres- Theembodiment of the invention shown in Figures 1 through 5 clining receiving and distributing chute 2 which is rotatably mounted on a vertical rotary shaft 1 operating in the bearing 8 mounted on the cover of the chamber H on the fixed table l2. The enlarged upper end or hopper portion of the comprises the outwardly de- I worm shaft l5 has comprises the worm nism with the intermittent discharge of batches of material or article's by the weighing machine, shaft l5 having'the worm M in mesh with the'wormwheel l3 on the lower end of the shaft 1 within the chamber 1 I. The

As a result, the chute 2 is turned from one receptacleto the next succeeding receptacle, where it stops while the next receptacle is receiving its charge of articles from the chute 2. Thechute 2 then moves on to the next receptacle, and these operations'continue until the weighing machine is stopped or the present apparatus is disconnected therefrom.

The receptacles l have hinged bottoms}, as shown in Figure 1, and more in detail in Figures 3, l and .5, which have'declining leaf spring tongues 3| on their lower sidetand' projecting'in the direction of rotation of the lower revoluble chute 23 which discharges to the packaging machine or the like; Depending latches on the receptacles I hold the receptacle bottoms closed until the forward edge of the discharge chute 23 moves into engagement therewith as shown in Figures 3 and 4 and disengages the latch to perwit the receptacle bottom to fall gravitationally the hopper ,23.

or similar. machine with which the contents of the receptacle into The receptacle bottom is then cammed into closed position by engagement of the rearward edge of the chute 23 with the declining spring 3| as shown in Figure 5, whereat the latch 30 acts to hold the bottom 4 closed until the chute 23 returns and opens it again;

The revoluble discharging chute 23 which disand empty; the

I charges to the packaging machine or the like is chute 2 is in receiving relation to thesupply con-- synchronized therewith by being driven by a belt or chain trained over the pulley 24 on the shaft 25 which extends into the chamber II: and has a worm 26 meshed with thewormwheel 21 which is attached to the upper end of the pivot pin 28. The lower end of the chute is secured to the lower end of the pivot pin 28 by means of the holder or bracket 29. a

The lower endLOf the chute 23 may discharge or deliver the articles directlyto the packaging machineor may deposit the articles onto a conveyor belt 34 leading to the packaging machine, as shownin Figure 1.

In some. instances ing machines do not single weighing or measurhave the speed or capacity to keep upwith a single packaging machine. In

machine may be associated with a single packaging machine, as illustrated in Figure 6. In this case on a common table 35 two circular groups of receptacles are arranged, each group being served by its own chute 2a, 2b, respectively, which are driven, from corresponding individual pulleys or chain wheels 24a, 24?), at speeds conforming to the performance of the weighing or measuring machine. The discharge chutes 23a and 23b alternately receive the batches of articles, so, that the corresponding conveyor belts 34a and 34.2) transfer the individual batches of articles or materials in alternate positions, onto the common conveyor belt 36 which delivers the batches to the packaging machine.

The embodiment of the invention shown in Figures 7 and 8 differs from those described above in that the revoluble chute 2c is provided with an internal conveyor belt 3'! which moves in the. direction of the arrowh, whereby the material or articles coming from the weighing or measuring machine. through the conduit Illa, falls on the belt 31 and is carried to the discharge opening of the chute, through which the material then falls into whichever of the receptacles. may be at the time disposed thereunder. This arrangement is especially advantageous for the handling of coherent or fibrousmaterial.

As shown in Figures 7 and 8, motion may be imparted to. the conveyor belt 37 by a belt pulley 38 whose shaft has a pinion 39 which drives one of the belt carrying rollers 41, 43 through the inter-engaged gears 40, 4'1, 42, 43 44, 45 and 45. The; chute 230 may also be provided with an internal conveyor belt 49 which is trained over the rollers 54 and 55, the latter being driven by the gear 4i through the gears 58,51, 52 and 53'.

It is; obvious that where the described transfer machine is used with weighing and packaging machines operating at regular coordinated rates, both of the revolving chutes must be driven according to the rates of operation of the weighing and packaging machines. Suitable mechanism, either electrically ormechanically operated can be provided for this purpose.

Where a weighing machine and a packaging machine associated with the present transfer machine operate at greatly irregular rates or at substantially uncoordinated rates, so that conditions of over accumulation of articles in or of starving of the receptacles develop, it is of course necessary to slow down or stop either the weighing machine or the packaging machine. Either of these controls. can be exercised either by a person in attendance or by the use of known mechanical or electrical means.

I claim:

.1. In a device for transferring articles or batches of articles between. a weighing machine and a packaging machine, said device comprising. an intermittently movable chute arranged to receive the articles, from the weighing machine, a plurality of linearly spaced receptacles into each of which said chute is arranged to successively deposit a weighed article or batch of articles. a receiver into which said receptacles are arranged to discharge, delivering means. for

conveying individual articles or batches of articles from said receiver to utilization means, and

intermittent driving means for driving said movable chute fro'm receptacle to receptacle in synchronism with the discharge of weighed batches from the weighing machine.

2. A transfer device for receiving a plurality of weighed articles or batches of articles from a weighing machine or the like and synchronously delivering the articles or batches of articles individually to a packaging machine or the like, said transfer device comprising a distributor including a. movable chute into which the articles or batches are individually received from said weighing machine, a plurality of linearly spaced relatively stationary receptacles with which said chute is arranged to register in succession in a. complete movement of the chute, drivev means for intermittently moving the chute and stopping it in registry to deposit an article or a batch of articles in each receptacle with which the chute registers whenever an article or batch of articles has been received in said chute from the measuring source in a corresponding position of the chute, a receiver into which the receptacles discharge, and deliveringmeans for individually conveying articles or batches of articles from said receiver to said packaging machine.
